To all whom it may concern:

Be it known that I, ETHAN I. Dorms, a

citizen of the United States, and a resident of Pittsburgh, in thecounty of Allegheny and State of Pennsylvanla, have lnvented certain newand useful Improvements in Rail-Joints; and I do hereby declare thefol-.

ingl their sections connected b splice bars or fis plates as now in use,an serve to reinforce or supplement such splice bar or fish plateconstructions.

A further object is to so construct a rail joint chair as to provide atransverse bolster which shall also serve as a seat for the meetends oftwo rail sections.

ith these and other objects in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out' in the claims.

In the accompanying drawings; Figure 1 is a perspective view of a railjoint show ng one embodiment of my invention; Fig. 2 1s a transversesectional view; Fig. 3 1s a longitudinal sectional view; Fig. 4 is atransverse section showing a rail in posit on; Fig 5 1s a perspectiveview of a rail omt showing a modified construction; Fig. 6 is an endview of the same; Fig. 7 is a transverse section; Fig. 8 a longitudinalsectlon and F1g. a side elevation of the form of the inventionillustrated in Fig. 5; Fig. 10 is a side view and Fig. 11 is aperspective view, of another embodiment of my invention; Fig. 12 is an.

, and 12; Fig. 14. is a transverse section of the same structure,showing a rail and fish plates in position; Fig. 15 is a side elevationof a further modification wherein a separate bolster is used; Fig. 15 isa perspective view of the separate bolster; Fig. 16 1s a plan view ofthe structure shown in Fig. 15, and Fig.

17 is a transverse section; Fig. 17 is a side elevation and Fig. 18 aplan view of another embodiment of my invention; Fig. 19 is an end view;Fig. 20 a transverse section and Fig. 21 a longitudinal section of thestructure shown in Figs. 17 and 18; Fig. 22 is a side elevation, andFigs. 23, 24 and 25 are sectional views illustrating another embodimentof the invention; and Figs. 26 and 27 are views illustrating othermodifications.

My improved rail joint chair comprises, in the embodiment of theinvention shown in Fig. 1 of the drawings, a plate 1 which may be madeof malleable iron or steel, and.

the chair may be made of metal capable of being pressed into shape withthe use of dies. The intermediate portion 2 of the plate 1 is depressedsomewhat below the horizontal plane of the end portions 3, as clearlshown in Fig. 3. The end portions 3 of the plate are adapted to restupon the ties and are pro vided with spurs-4 to engage the latter, saidend portions being preferably also made with holes 5 for theaccommodation of spikes. The depressed intermediate portion 2 of theplate will span the space between ties and is provided centrally with athickened portion forming a transverse bolster 6, the latter alsoserving to receive and provide a bearing for the meeting ends of tworail sections. At respective sides of the intermediate portion two ofthe plate, upwardly projecting strengthening webs 7 are provided. Thesewebs may have convex upper edges extending from end to end .of theintermediate por tion 2 of the plate, and said webs are rovided withlateral flanges 8 projecting rom their convex edges. The flanged websconstitute compression members to sustain the load, brought to bear uponthe bolster 6.

My improved joint chair will eflectually sustain the strain brought tobear upon the meeting ends of rail sections when the joint comes betweenthe ties and will operate to reduce to a minimum, the hammering of therails at the joint,efiicient trussed bolsters, such as indicated at6-7-8, being provided to receive and sustain the meeting ends of therail sections.

In the form of the invention shown in Figs. 5 to 9, the curved webs(project downwardly .as indicated at 9 an provided at their lower curvededges with flanges 10.

The flanged truss thus formed constitutes a member as shown in Fig. l,to sustain the strain which will come upon the bolster 6. In thisconstruction, the connection between the bolster 6 and webs 9 may befurther strengthened by means of ribs 11.

Tn the construction shown in Figs. 10 to 14, the central portion of theplate is removed as indicated at 2 and at respective sides of this opencentral portion, vertical webs 12 are formed so as to project above andbelow the horizontal plane of the plate,said webs being provided attheir free upper and lower edges with lateral flanges 131-l. A bolster15, which may be made in the form of an T-beam, extends across thecentral space 2 from one web 12 to the other and is supported by saidwebs. In Fig. it of the drawings, l have shown the bolster integral withthe webs and the bolster 15 is so proportioned that its upper face shallbe in line with the upper faces of the portions 3 of the plate andconstitutes a seat for the meeting ends of the rail sections. Ifdesired, holes 16 may be made in the portions 3 of the plate to reducethe weight of the latter. The plate or chair in this form of theinvention, may be provided with spurs t and spike holes 5, as in theconstructions previously described.

In the embodiment of the invention shown in Figs. 15 to l? the railjoint chair comprises three parts,viz. two truss members and a bolster.Each truss member comprises two plates l7l7 connected by a web 18extending above and below the plane or the plates,-said webbeingprovided at its free upper and lower edges with lateral flanges i9,26. The truss members are suitably spaced apart on the ties, andconnected by a transverse bolster 21 which, in this case, is madeseparate from the truss members and passed through holes 22 in the webs18. The bolster 21 may be made in the form of an l-beam having itsbottom portion curved or bowed downwardly, and provided at respectiveends with transverse ribs 23 which serve to prevent displacement orspreading of the truss members.

Tn the construction shown in Figs. 17 to 21, the intermediate portion ofthe plate or chair is cut away as indicated at 2", and webs 2% areformed at respective sides of said central open portion. These webs areprovided at their upper edges only with lateral flanges 25, and thebolster 26 is, in this construction, made integral at its ends with thewebs 24;. Openings 2? may be made in the plate or chair to reduce theweight of the same.

Figs. 22, 23, 2d and 25 show splice bars 28 which may be of cast metalhaving webs 29 to depend between the ties and provided at their loweredges with lateral flanges 30 which may project outwardly or said flanes may project inwardly as well as outwar y.

nee les The webs 29 may be provided with holes 32 to accommodate abolster 33, which latter may be the same in construction as that shownin Fig. 15*.

Tn the construction shown in Figs. 26 and 27, the intermediate portionsof the respective truss members have a cross section re sembling that ofan il-beam. The webs 34: project above and below the plane of the endportions of the chair,the upper edge of each Web being made straight andprovided with lateral flanges 35, 35 projecting in opposite directions,and the lower edge of each web 34; being made curved and pro= vided withflanges 36, 36 projecting in opposite directions. The webs 34 areprovided with openings 37 to receive the ends of a bolster 38, theconstruction of the latter being the same as that shown in Figs. 15* and2d.

@ther changes might be made in the details of construction of myinvention with out departing from the spirit thereof or limiting itsscope and hence I do not wish to restrict myself to the precise detailshere in set forth.

Having fully described my invention what I claim as new and desire tosecure by lhettors-Patent, is

l. A rail joint chair comprising two par allel' vertically disposed webshaving lateral flanges at their tree edges and constituting trussmembers, and a transverse bolster ere tending from one truss member tothe other. and sustained by said truss members, said transverse bolsterconstituting a member or? the chair and adapted to receive the meetingends of rail sections.
